Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for device identification, such as using card numbers or one-time-passwords (OTPs), face challenges like data leakage and difficulty in application across various fields, while the increasing use of drones necessitates effective anti-drone technologies for distinguishing friend or foe drones.
Innovation Solution
A method and apparatus that utilize a chip unique value-based virtual code, generated without a separate identification procedure, which is unique and changes periodically, allowing for secure device identification without exposing actual codes, and can be applied to various devices like IC cards, SIM cards, and control devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If actual card numbers are recorded on card surfaces, then user identification is enabled, but data leakage occurs when codes are visually exposed or transmitted
Solution Approach 1:
The patent introduces a virtual code as an intermediary that replaces the actual card number in transmission and storage. The virtual code generation means creates a virtual code based on the actual card number and transmission time, which is then used instead of the actual card number during transactions. This intermediary layer prevents direct exposure of the actual card number while enabling identification and transaction processing.
Solution Approach 2:
The patent creates a virtual copy (virtual code) of the actual card number that serves the same identification function. The virtual code is generated by encoding the actual card number with time-based parameters, creating a functional copy that can be used for transactions without revealing the original card number. This copy mechanism allows the system to work with surrogate identifiers rather than sensitive actual values.
2Reliability
If one-time-passwords (OTP) are used for user identification, then data security is improved, but login procedures are required which limits application across various fields
Solution Approach 1:
The virtual code generation means operates autonomously to generate virtual codes based on the actual card number and current transmission time without requiring user login or external verification. The system automatically creates and manages the virtual codes, performing the security function itself rather than requiring external authentication procedures. This self-service mechanism enables seamless operation across different applications without adding login steps.
3Reliability
If conventional identification methods are used, then device identification is achieved, but separate identification procedures are required which reduce efficiency
Solution Approach 1:
The patent combines the identification function with the code generation process. The virtual code generation means integrates device identification capabilities directly into the virtual code creation mechanism, so that device identification occurs simultaneously with virtual code generation rather than as a separate step. This merging of functions eliminates redundant identification procedures and reduces overall processing time.
